TPS2379DDAR

Overview

The TPS2379DDAR is a Powered Device (PD) interface controller compliant with the IEEE 802.3at Power over Ethernet standard. It operates within a supply voltage range of 0 V to 57 V and features a maximum on-resistance of 750 mOhms. The device includes an internal current limit set to 850 mA and draws a typical operating supply current of 285 uA. Designed for surface-mount installation, it utilizes an SO-PowerPad-8 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

Complies with IEEE 802.3at PoE standards for high-power powered devices
Integrates an external gate driver capability for load control
Provides built-in current limiting protection at 850 mA

Applications

High-power Powered Device interfaces in IEEE 802.3at networks
End-to-end PoE systems requiring external hotswap MOSFET integration
Network infrastructure equipment demanding standardized PD power management

Procurement Notes

Verify the specific suffix 'DDAR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the component meets RoHS requirements for your target market. Ensure the design accommodates the SO-PowerPad-8 thermal pad requirements for proper heat dissipation during operation.

Selection Notes

Select this component for applications requiring strict adherence to the IEEE 802.3at specification. The integrated gate driver simplifies designs needing external power switches for higher current loads. Consider the 750 mOhm on-resistance for efficiency calculations in low-voltage PoE scenarios.

Part Context

This part belongs to the Texas Instruments TPS2379 series, which focuses on PoE Powered Device interfaces. It serves as a specialized solution for network devices requiring reliable power delivery over Ethernet cabling while maintaining compliance with international networking standards for safety and interoperability.
